On Christmas day, the popular Slay The Spire mod Downfall encountered a security breach, exposing users to a malware attack that targeted their personal information. Hackers successfully distributed malware through Steam, affecting users’ passwords for internet browsers and messaging services like Telegram and Discord. This article delves into the aftermath of the breach, highlighting the potential risks and offering recommendations to affected users.
The breach allowed hackers to exploit a vulnerability in the Downfall mod and distribute malware via Steam. Users who launched the mod during the attack were met with a deceptive “Unity library installer popup.” This malicious software aimed to pilfer passwords from various platforms, including Windows local login, Google Chrome, Yandex, Microsoft Edge, Mozilla Firefox, Brave, Vivaldi, Telegram, Discord, and potentially any files with the term “password” in their filenames.
Although some antivirus software failed to prevent the execution of the malware, it successfully prevented the transmission of its payload over the internet. As a result, users were not immediately harmed by the attack. However, affected users must remain vigilant and take precautions to minimize potential risks.
Users have reported the creation of suspicious files in different locations on their hard drives, some of which are detailed in the official announcement. However, a crucial piece of advice from the developers is to refrain from investigating these files while connected to the internet. Disconnecting from the internet creates a temporary shield against potential attacks, allowing users to examine the suspicious files with reduced risk.
To safeguard personal information, individuals who encountered the Unity popup should promptly change their important passwords, particularly those that are not protected by two-factor authentication (2FA). Two-factor authentication provides an additional layer of security by requiring users to verify their identity through a separate device or platform.
Despite this unfortunate incident, Downfall remains a highly regarded and beloved Slay The Spire mod. The developers have responded to the breach by redirecting their efforts towards creating a standalone auto-battling Chess roguelike named Tales & Tactics. This new project promises to continue providing engaging and immersive gameplay experiences.
The cybersecurity breach that impacted the Downfall mod serves as a stark reminder of the risks associated with online gaming. Users must remain cautious and proactive in protecting their personal information. By following the recommendations provided by the developers and staying informed about potential security threats, individuals can continue to enjoy their gaming experiences without falling victim to malicious attacks.
